WebFracture involvement of the frontal sinus has been estimated to occur in 2% to 12% of all cranial fractures, and severe fractures occur in 0.7% to 2% of patients with cranial or cerebral trauma. Approximately one-third of fractures involve the anterior table alone, and 60% involve the anterior table and posterior table and/or ducts. WebThe use of armor or shielding may modify injury patterns from bullets. Body armor may reduce or eliminate penetration of tissues by a projectile, but not eliminate tissue damage. The term 'behind armor blunt trauma' defines the tissue damage from a pressure wave generated by a high velocity projectile striking body armor.
